Multiple NAT translations with NVI (NAT Virtual Interface)

NVI removes the inside & outside terminology. With NVI multiple interfaces can participate in the translation. Before you cannot have translation with two INSIDE interfaces, NVI fixes that. http://www.cisco.com/en/US/docs/ios/12_ ... natvi.html

Basic configuration(no VRF enable):

int fa 0
  ip nat enable
int fa 1
  ip nat enable
int serial 0
  ip nat enable

ip nat source list 50 interface serial 0 overload //translate fa 0 & fa 1 lans out serial 0
ip nat source list 125 interface fa 0 overload //translate fa 1's lan out fa 0
ip nat source static tcp 172.168.50.10 80 interface serial 0 80 //translate web server out serial 0
